VENTILATOR FOR FOOTWEAR.

Application mea march 2s, 1917. seal No. 158,011.

To all whom 'it may concern.'

Be it' known that I, JOHN V. HAGs'rRoM, a citizen of the United States,residing at H adlock, in the county of Jefferson and State ofWashington, have invented certain new and useful Improvements inVentilators for Footwear, of which the following is a specification.

This invention relates to boots or shoes, nd particularly to Ventilatingmeans there- The object of the invention primarily is to provideimprovements in means for introducing air to the foot portion of a bootor shoe, so as'to render the foot wear morecomfortable, and to obviatefoot soreness. A further object of the invention is to provideVentilating means for use in connection with boots or shoes, which willnot create discomfiture to the wearer of the boot or shoe, and whichwill not detract from the appearance of the foot wear. A still furtherobject is to provide a Ventilating attachment for foot wear which isarranged in such manner that the movements of the foot within the shoewill operate to introduce to or eX- pel air from the interior of thebootv or shoe.

A still further and particular object of the invention is to provide aVentilating attachment of the character set forth, which is eX- tremelysimple and inexpensive o f construction, which is capable of beingreadily applied to a boot or shoe without appreciably departing from thepresent construction of the foot wear, and which will prove ,thoroughlyeii'icient in attaining the ends set forth.

With these objects in View, together with others which will appear asthe description proceeds, the invention resides in the novel formation,combination, and arrangement of parts, all as will be described morefully hereinafter, illustrated in the drawings, and particularly pointedout in the claim.

In the drawings Figure l is a side elevation of a boot, illustrating theapplication of a Ventilating device constructed in accordance with theinvention;

Fig. 2 is a vertical sectional view taken through the foot and upperportions of the boot; and Fig. 3 is a transverse sectional View taken online 3 3 of Fig. l.

Referring to the drawings, 5 indicates the foot portion of the boot, and6 the upper thereof. The invention in the present instance isillustrated and described as being used in connection with rubber boots,but it will be understood that the invention is not restricted to footwear of this particular type and may be employed with e ual eliiciencyin connection with footwear o Varied sizes, types, and designs.

The boot upper is provided preferably in one side with an outwardlydepressed portion. indicated generally at 7. This depressed portionextends from the upper edge of the boot upper to the foot portion of theboot, and is of narrow width and shallow depth. Arranged within thisdepressed portion is a Ventilating tube 8. This tube may be formed ofrubber, rubberized cloth,

or any other suitable material, preferably, however, a material whichwill be flexible, and water and air tight. The tube iits snugly withinthe recess formed by the outwardly depressed portion 7 and communicatesat its upper end with the atmosphere and at its lower end with theinterior of the boot and preferably adjacent the instep or heel portionsthereof. It will also be observed that the lower end of the Ventilatingtube terminates slightly above the sole of the foot wear.

ln order that a Ventilating device of this character will not causediscomflture to the wearer, the tube is positioned between the bootupper and the lining therefor. The lining is indicated at 9, and thepliability of the tube 8 permits the lining to lie smoothly against theinterior surface of the boot upper so as to not bulge `or break thesmooth continuity thereof.

The lower end of the Ventilating tube communicates with the interior ofthe boot, as has been before stated, adjacent the heel or arch portionsof the foot. It is well known that in walking these portions of the footmove appreciably within the shoe. Such movements of the heel and archportion of the foot obviously create movements in the air present in theshoe, and by so locating'the inner or lower end of the ventilating tube,the disturbance of the air within the shoe is transmitted to the air inthe ventilating tube. The particular arrangement creates a constantinward and outward movement of air within the tube 8 when the foot isbeing moved, and therefore the intei rior of the foot wear's perfectlyventilated.

By s0 constructing the boot, diseases of the feet will be overcome.

While the present is a disclosure of what I believe to be the preferredembodiment of the invention, it is to be understood that the inventionis not limitedthereto; but that .various changes may be made in theconstruction, arrangement, and proportion of parts,

without departing from the spirit of the in vention, as deined in theappended claim,

Whaty is claimed is In a boot, outwardly preed portions inv wardlypressed portions 'and between theY i said upper and the lining oftheboot.,- the inner end lor' said tube communicating with the interior ofthe boot above the sole thereof and substantially midway between therear of the heel andthe arch of the boot, and the said tubes being ovalin` cross section so as to bewholl confined within the spacei providedby `sald outwardly pressed portions. 1

In testimony whereof I aiiix my signa- Iture in presence of twowitnesses.
